 ## Proposal
-All publicly accessible WordPress post types can become active for ActivityPub federation when selecting a transformer available for the relevant post type. The transformer determines the target ActivityPub object type, which can vary depending on variables like the post type or post format. If there is no specific transformer available for a given post type, it cannot be assigned through the user interface.
